Answer:
- x = -3 or x = 4
Step-by-step explanation:
The equation is:
- 4x² - 4x - 48 = 0
Simplify and solve for x to find the zero's:
- x² - x - 12 = 0
- x² + 3x - 4x - 12 = 0
- x(x + 3) - 4(x + 3) = 0
- (x + 3((x - 4) = 0
- x = -3 or x = 4
The solution(s) is (are) the point(s) of intersection of the graph with the x-axis.
